Various cycling computer from the test of Sigma

A bicycle speedometer is primarily there to measure the speed. This appears live on the screen and gives a continuous overview. The maximum speed, average speed, trip time, trip distance and distance traveled are standard displays a good cycling computer. The better the model, the more functions are contained.

  • A calorie display,
  • an altimeter,
  • measuring the crank revolutions
  • and vital signs (heart rate)

can also be determined. The latter is in this case through a plug, such as a waist belt or chest belt of a heart rate monitor , achieved with built-in sensor. Models should have a water resistance, so that the cycle computer mudbath must not be removed directly. Useful functions such as service interval display can be integrated. As with a car, the user is here driven by a certain number of kilometers of the Note for next inspection shown.Integrated memory chips hold data even when a battery or battery change . Because of reconfiguration in most models is not necessary.

Statistical data transfer to PC

Who subsequently wants to analyze its routes and its statistics professionally, has in some bicycle speedometers the ability to transfer them to the PC. With such a function can keep his trips and his training effect permanently in focus.

Bike computer with GPS reception

Gets the cycling computer’s route information on the GPS system, and altitude and all routes can be displayed on the display. Ascents and descents can be later analyzed and evaluated on the PC.

Thus, the cycle computer also displays the correct values, you have to configure it. This requires the tire circumference. This measured, it is entered into the computer. On the number of revolutions of how many meters can now be calculated, are supplied.

Front tire with rule off

If one has no flexible tape at hand, the extent across the radius can be determined. The formula for this is: circumference = 2 x pi x radius. The whole thing is calculated in the unit centimeter (cm) and for «pi» you replace the value 3.14159. The radius, we determine from an outer side of the tire to the center of the hub. What values have to be entered, one reads in the corresponding operation display of the bicycle speedometer.

Example calculation: 2 x 3.14159 x 33 = 207.3449 cm circumference.

Bike Computer with cable or radio

Bicycle computer with a wireless connection are quickly mounted to the bicycle and require no costly laying a cable. A disadvantage often the wireless connection and data transfer even be enumerated. Interference of the environment can have a negative effect on the correct transfer of data.

Bike Computer with Heart Rate Monitor

Anyone wishing to use the above-mentioned function to monitor the heart rate, which has to decide on a model that offers an additional module. Usually this is a waist belt to which a sensor is mounted for the measurement. This belt strapped to while driving around the chest, the heart rate and the heart rate can be determined and recorded.
